I'm not going to go into the substance of the debate here (you can read a summary over at Unlearning Economics) but here's an interview with Steve Keen where he covers the basics for the non-wonkish and does a pretty good job of deflecting attention away from the process stories which seem to cling around Krugman. The interview starts about 2 minutes in.

Here at MoneyScience, for good reasons, I don't tend to take a view on academic scuffles in economics. The evident failure of orthodoxy and a tendency toward scientific scepticism means that I generally view most economic positions with suspicion, so I leave it to you to make at your mind. As ever, comments are appreciated.
